This is a good article. Follow the link for more information. It provides python for data scientists pdf that enable clear programming on both small and large scales. Van Rossum remains Python’s principal author.

In December 1989, I was looking for a “hobby” programming project that would keep me occupied during the week around Christmas. With this release, the development process became more transparent and community-backed. 3 December 2008 after a long testing period. Python 2 code to Python 3. 2015, then postponed to 2020 out of concern that a large body of existing code could not easily be forward-ported to Python 3. In January 2017, Google announced work on a Python 2.

Rather than having all of its functionality built into its core, Python was designed to be highly extensible. This compact modularity has made it particularly popular as a means of adding programmable interfaces to existing applications. CPython that would offer marginal increases in speed at the cost of clarity. Python script into C and makes direct C-level API calls into the Python interpreter. An important goal of Python’s developers is keeping it fun to use. To say that code is pythonic is to say that it uses Python idioms well, that it is natural or shows fluency in the language, that it conforms with Python’s minimalist philosophy and emphasis on readability.

Addition, subtraction, and multiplication are the same, but the behavior of division differs. There are two types of divisions in Python. They are floor division and integer division. Parentheses are optional for tuples in unambiguous contexts. In Python 3 and 2. Strings delimited by single or double quote marks.
